T0 all'whomtmay concern: Y

Be it known that' I, DENNIS J. ALLEN, a citizen of the 'United States, residing at Binghamton, in the county ofwBroome and State of New York, have inventedcertain new anduseful Improvements in Railway SignalDevices, of which the followingisa specification. t y 1 This invention relates to signal devices, more particularly to apparatus employed in railway operations, and has for one. of its objects to provide a device of this character whereby the engineer in the cab of a locomotive is warned of the approach to a semaphore, and signals both aural and visi-i ble transmitted to him, the signals, preferably being duplicates of those imparted by the semaphore.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and de-. scribed and then specifically pointed'out: in the claim, and in the drawings illustrative of the preferred embodiment of the invention, j

Figure 1 is a diagrammatic view of a sec tion of railway track and a plurality of semaphores, with the portions of the improved signaling associated therewith,

Fig. 2 is a diagrammatic detail of the portions of the apparatus associated with the locomotive and the engineers cab, together with one of the semaphores alongside the track.

Fig. 3 is an enlarged face view of the casing containing the portion of the mechanism in the engineers cab.

The track rails are indicated at 10 and two semaphore standards at 11, the latter being located at the terminals of a block, each semaphore indicating the beginning and ending of each block.

The standards 11 carry the usual swinging signal imparting arms 12 and 13.

Located adjacent the rails 10, preferably between them, and also adjacent each semaphore standard, are contact members 14, which for illustration are shown formed of sections of railway rails.

Other contacts 15 are also located intermediate the semaphore standards, as shown in Fig. 1.

Attached to the locomotive are'other contacts adapted to engage the contacts 14 and 15 as the locomotive passes over the track.

. S cification of Letters lratent i jAug. 23, Application filed September 7,1920; I Serial No. 408,429. I a

Fig. 2.

The frame of the truck carries brushes 20 1n constant'contact with the disks 16,.to which the conductor wires are connected.

Located inthe engineers cabis a casing 21 carry ng the operating devices whereby the. positions of the main semaphore arms are duplicated inminiature on the casing 10, so that'the-engineer will have before his eyes a set of the arms set in exactly the same position as those on the main semaphores alongside the "track outside.

..The mechanism in the casing 21 comprises 7 coacting. shafts 22 and 23 carrying arms 24 and 25 duplicates in miniature of the main arms 12 and 13, and externally of the face of the casing. 7

Attached respectively to the shafts 22 and 23 withinthe casing are pinions 26' and 27, and pivotediat 28 and 29 are arms 30 and, 31 each having a gear segment at one end engaging respectively with the pinions 26 and'27.

Located within thecasing 21 are electromagnets 32 and 33, and pivoted at 34 and 85 are armature levers 36' and 37 within the influence of the magnets. The armature lever 36 is coupled at 38 to the segmentcarrying arm 30, while the armature lever 37 is frame 40 is a bell or gong sounding mechanism of approved construction, and represented as a whole at 41. The sounding mechanism is adapted to be controlled by an electromagnet 42 arranged to operate a releasing lever 43.

The magnet 32 and the sounding mechanism are in electrical connection by wires 44 through a suitable source of power, for instarice a battery represented conventionally at 5.

The magnet 42 is in electrical connection with frame 19 and one of the brushes20 by conductor wires 46. a

The magnet 33 is in electrical connection with the frame 19 of the truck and the other any suitable form, but forillustration' and indicated at 48 in vthe circuit of the con! 7 ductor wire 47.

Located in the paths of the arms 12 and,

13, are circuit closing devices 49 and 50,

the latter being connected by wires 51 with f tion is disclosed in the drawings and set the line rails 10 and contact rails 14 and 15 and through a battery 52, or other source of power.

The tracks 10 are provided at suitable intervals with insulated rail joints 53 which separate the track into blocks.

The mechanism in the casing21 is spring controlled, and a hand 54 is attached to the mechanism externally of the casing, to indicate the condition of the spring, to-notify the engineer when it requires rewinding.

By this arrangement, when the locomo-' tive enters a block, the miniature semaphores 24 will be disposed in the same rela tive position as those on the post or standard outside. For instance if the 'upper arm 12 is elevated to indicate caution, the arm in rising to horizontal or caution position, will engage the contact 49 and close the circuit through the wire 51cause the corresponding miniaturev arm 24 in the engine cab to assume the same position, and at the same time sound the hell or buzzer 48, thus informing the engineer of condition of the main semaphore. i

Then on the other hand if the lower arm 13 or the one to indicate danger,,is actuated, the contact 50 will be engaged, and the corresponding miniature arm 25-to be correspondingly actuated, as will be obvious.

The same operations will take place when the locomotive passes over the intermediate contacts 15, so that the engineer can be kept 7 position in the required, depending on circumstances, or

the contour of the line."

The preferred embodiment of the invenforth the specification, but it will be understood that any modifications within the scope of the claim may be made in the'con struction without departing from the principle of the invention or sacrificing any of its advantages. 8

I claim:

Ina signal apparatus, a semaphore device tromagnetfor said arm, an armature sw1ng-' lng atone end ad acent sa1d magnet, an eX-- tension from saidarmature and connected 7 to said arm, an elongated electrical contact ad acent the rallway line and in electrical connection with the line semaphore, an electric contact carried by the moving train in' position to engage the elongated contact, and electric connections between sa1d electric contacts and the electrom'agnet, whereby the' miniature semaphores are moved into the same relative position as the line semaphore when the train contact engages the elongated contacts. 1
